of the person manipulating the knocker.

To overcome this andother objections, it is one object of the invention to provide a combination device of the character described of improved construction whereby a bell, buzzer or indicator will be actuated Von relatively slight movements of the han` dle ofthe door-knocker.

Another object of the invention is to provide an improved electrically operated bell,

- 2o buzzer or indicator, adapted to be readily installed to cooperate Awith existing door- 4 knocking installations without altering or modifying the latter.

A. further object of the .invention is to provide an installation of the character described which is rugged, adapted to withstand the roughest usage and may have electrically operated portions interconnected so as vto be practically'incapable of being put out of order by the severest banging with the knocker handle. r y

Still another object of the invention is to provide devices of the character described comprising few and simple parts, which shall be relatively cheap to manufacture and install, inconspicuous, and practical and eiiicient to a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be eXempliied'in the construction hereinafter described and of which the scope of application will be indicated in the following claims. Y f

In the accompanying drawing, in which is shown various possible illustrative embodiments vof this invention,

Fig. 1 is a plan cross-sectional view of a door jamb and fragmentary portion of a door with an installation of an improved combination door-knocker and an electrically operated bell embodying the invention, the bell, batteries and connecting wires being shown diagrammatically.

Figs. 2 and 3 are cross-sectional views taken on lines 2--2 and 3 3, respectively, in Fig. 1, and

Figs. 4 and 5 are plan and elevational cross-sectional views, respectively, of a modified construction of the invention, Fig. 4 corresponding to a section taken on lines 4 4 in Fig. 5.

Referring in detail to the drawing, 10 denotes a knocker secured in position on the exterior side of a door ll in any well understood manner. The door 11 may be mounted for swinging against the jamb 12il of a (llior frame l2 by means of suitable hinges The knocker 10 preferably is of artistic design and may be of any well known construction. As here shown said knocker comprises a striker or handle 14 formed with interconnecting arms 14, which are pivoted at their upper ends 14b on a pin 16 support? ed by a lug 15'r1 of a backing piece 15. The backing piece 15 has a raised stud or anvil l5b on its side facing the handle at the end opposite said lug for receiving the blows of a protuberating boss or weighted head 14c of the handle.

The knocker 10 is actuated in the well known manner either by swinging the handle 14 and causing the head 14c to beat against the anvil 15b or by raising the handle and permitting it to fall by gravity so as to strike said head on the anvil. Frequently the knocker is actuated by a timid person who lightly taps therewith, or. one who uses insuilicient force to make known to the occupants in a remote place in the house the presence of the person knocking. It is one dominant purpose of the invention to provide means of novel construction to be simultaneously actuated on relatively slight displacement of the handle 14 from its lowered "f control plunger 2()a therefor, and conductor v ity. or the rcree of swinging the hand e b member 21 extending through a suitable recess 11 of the door 11.` Said members terminate in end contacts 21bon the door, edge-y surface 11'b as shown in Fig. 1. Spring control iingers 22 mounted in the jamb 12a are provided to detachably connect with said contacts on swinging the door 11 shut to form a circuit with a signal apparatus, either of the indicating or alarm type, as for ex ample, a bell 23 and lead wires 24, connecting with a suitable electric power source such as the battery 25 as shown in'lig.l 1.

The recess 11 ispreferablybored to extend into the door from the edge surface 1.1b and is vcircular inV cross-section as shown in Figs. 2 and 3. Said recess is proportioned to snugly` receive therein the conductor members 21 and switch 20 assembled asa unit structure by a stii interposed bar 26 and interconnecting spaced` bands 27. Said bar and bands contact ,with the walls of the recess and firmly retain the'unit, structure in the .position as is clearly7 seen from Figs. l and To prevent relatlve rotation of the switch in the recess the free exposed ends 21b of the member 21 are fixedly secured ggainst the door,edgesurface 11 by screws For resiliently-sup orting the contacts 21a for movement to an from each other the inner ends of portion 21 carrying the contacts, are formed of springV material and inl be made of insulated circular-wires or rib ns. u

The plunger 20 which extends from recess *11 through the door, has its inner end 20b abutting on' of portions 21c of the members 2 1 so that w' en' the exposed end 20 of said plunger is forced intoward the door by press'ure'exerted on the handle in its normal position of re ose,as shown at 29 Vdue to rava user, the contacts 218L are separated an the switch 20 is o ened. The slightest movement of the han out of said normal position of repose releases the portion 21c of member 21 permitting it to sprin thek contacts 21 together .and thereby c osing the circuit through the switch 20.

The plunger 20 is mounted to reciprocate through a bearing member 20E and preferably is limited in its movement by providing stop nut20", the outer free end'20" of said plunger being'iitted with an adjustable capnut 20d having a locknut 2()t which is adaptedl to set the rswitch and 'theknocker-handle in proper cooperating relation. The bearing member 20 may be extended rearwardly as at 20h to form a support for the member portions 21 as shown in Figs. 1 and 3 thereby facilitating the assembl and installation.

The operation of t e improved doorknocking installation will now be apparent. With the door swung open as shown in Fig. 1, the electric system will be o en circuited at the spring fingers 22. owever, en closing theldoer the witch 20 will be connected in circuit as is readily understood. The handle 14 when swinging from its normal` of :.1 shown in full lines in Fig. 3 wh relieves the plunger 80 20 from the fonce exerted by' the weight` of the handle pressing it in tothe recess 11 and permits` the switch contacta .21.* income toi-s gather for closing the .switch aimait thereby causing the M1123 'to ring. the handle and its return to its nnrmalposition of repose, the circuit 'will again.` be opened at the switch contacta 21* `and the bell 1 Ringing, I p j In Figs. 4 and 5 ammhed construction m embodying-the inventionis shown. Here the knackenmay be 'to knodcer 10 described above and shovmin Figs. ,1 .and 3, inclusive, with the exception that the plunger 12D 'is slidingly mounted in a henrnu ing memberpositionedlabove the uppi` ivoted end 114b of thknneka' handle lll. id handle end 114;b istonned with a. nam portion 114* which abats the catnut 129l of the anger. Thus when the dle 1141.100 is li from its normal position of repose for m the langer-'filA pressed into the recess 11* oiftha r11 lld carries ik contacts 121* on the resilient members 121 together com il the switch @m5 circuit.l On return of the i e, the mntacts 121l are again f as is clearly seenffromF-igA.- 1

f It will thus be seen that there is provided devices in. which the several objects of this .no invention are achieved which isfwel adapted to meet the conditions ol practical,

Asvaroas .LY-..1 ible naighte4 made ofthe a ve inventbm'and asvaunsms changes t he madsin the embodiment above setffwth, it is thi: all matter herein sctorth 'or shown im the accompanyingfdrawing is to be interpreted A as illustrative and not in a limiting sense.
